About this 0.97ct lab-grown heart diamond

This 0.97ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG804673282 or 804673282. Listed at 18 retailers as of November 4, 2026, with prices from £137 to £1,133, a £996 spread on the same certified stone. Brilliant Earth lists it at £1,133. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
